v 1.1 - Some corrections and information about the haircut brothers.
v 1.0 - Initial version.

This is a VERY short FAQ to fill in a quite specific gap I've found in all other 
Pokemon FAQs out there. The purpose of this FAQ is to list how exactly do your 
actions affect the Happiness of your Pokemon. In short, every Pokemon has a hidden 
stat or value which is usually referred to as Happiness (the term "loyalty to its 
trainer" is, however, used in Pokemon Stadium GS). 

The most interesting consequence to this is that certain Pokemon only evolve to 
their next form when that stat reaches or surpasses a certain value after leveling 
up. Which Pokemon are these is conveniently explained in other FAQs, so I won't 
repeat them here. Also, I won't explain what the actions below are: if you are 
serious about making a Pokemon happy, you should know about all of them, and 
again, they are outlined in other FAQs as well.

The needed value of Happiness for a Happiness Evolution is 220 (yes, 220, not 218 
as listed elsewhere). However, the evolution is only triggered after a Level Up. A 
Pokemon evolves when they have 220 happiness AFTER a Level Up. The reason for this 
remark is that Leveling Up itself raises Happiness (generally 5 points, but 
sometimes only 3. I'm not sure what determines this, but I'm pretty sure it isn't 

How was this FAQ done? Easy. Using a GB emulator, I just scanned the memory 
address where the value is stored, and checked how actions affected it. Believe it 
or not, though, I play the game on a real Gameboy, which made things a little 
harder since I had to search for saved games all over the 'net :/ As a consequence 
of this, some of the stuff (namely Daisy and some other) had to be tried on 
Pokemon Crystal (only saved game I found near the end), but I doubt the values 
were changed (for the record, the haircut brothers were tried on BOTH Gold and 

This should be obvious, but all stuff listed under "rumored to affect happiness, 
but proved wrong" has been tested thoroughly as well.

                               Happiness values                        
| Pokemon is captured with Friend Ball           | Starts at 200                |
| Pokemon is captured with any other Ball        | Starts at 70                 |
| Pokemon is traded                              | Resets to 70                 |
| Amount of happiness needed for Evolution       | 220                          |

Well, after some more testing with the haircut brothers, I've discovered that you 
can actually know what points did the haircut you just took give to your Pokemon.
 - If it says "XXX looks a little happy." you received 1 point.
 - If it says "XXX looks happy."          you received 3 points. 
 - If it says "XXX looks delighted!"      you received 5 points (older brother) or 
10 points (younger brother).

While checking the above, I noticed that, actually, the younger brother gives 1 
point most of the time, and 10 points very rarely, while the older brother gives 3 
points more often than 1, and 5 points more frequently than his younger brother 
does 10. So I thought it might be that the older brother isn't as bad as it first 
seemed, and maybe, he could even be the better one after all. I decided to do some 
sampling and after taking about 150 samples, I found that the percentages are 
approximatelly as follows:

  Younger brother                Older brother
  ---------------                -------------
   1 point  : 70%               1 point   : 20%
   3 points : 20%               3 points  : 60%
  10 points : 10%               5 points  : 20%

So the average points are:

Younger brother : (1 x 0.7) + (3 x 0.2) + (10 x 0.1) = 2.3 points on average
Older brother   : (1 x 0.2) + (3 x 0.6) +  (5 x 0.2) = 3   points on average

Younger brother's average points per 100 yen : 2.3 / 3 = 0.7
Older brother's average points per 100 yen   : 3   / 5 = 0.6

Note that (assuming the sampling I performed actually represented the real ratios) 
the younger brother is STILL the better of the two, but not by as much as I first 
Also note that the actual points per 100 yen ratios are much lower than what I 
estimated :( 

Of course, the best option is letting Daisy (in Pallet Town, from 3PM to 4PM 
everyday) groom them, since that gives 3 points twice and it's absolutely free. 
However, you don't reach Pallet Town until very late in the game. Oh, and yes, you 
can groom the same Pokemon twice and he'll gain 6 points total.

Also, if it's a catchable Pokemon, using a Friend Ball to catch it will make a 
HUGE difference (200 instead of 70!). It's a pity, though, that most Pokemon that 
evolve by happiness are in fact not catchable :( . The only one I can think off 
the top of my head is Golbat (to Crobat).

And finally, note that stat-increasing items actually raise happiness very little 
for their price, making it more of a "nice side effect" than an "strategic 
exploitable bonus". 

Final note: I don't want mail. I haven't ommited my e-mail address for nothing, 
you know. If you happen to obtain it by other means, don't use it. Oh, and I eat 
little children alive.
